Figs. 25−30 , 45−46

Types. Holotype: male from Cueva Mogote , Tercer Frente, Santiago de Cuba, Cuba (20°12'49.10"N, 76°18'31.93"W), under rocks, March 24, 2013, F. Cala col., deposited in IBSP164686. Paratypes: two females with same data as holotype, deposited in IBSP164687 and IBSP164688.

Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Male specimens of L. mogote sp. nov. resemble those of L. maisi sp. nov. and L. taino by the globose palpal tibiae in the male palp, but can be distinguished by the slender and curved embolus ( Figs. 25−26 ). The females resemble those of L. caribbea and L. cubana by the shape of the spermathecae, but differ by the very long receptacles, of which the inner one is twice as large as the outer one, on a short base ( Figs. 45−46 ).

Endites orange distally and yellow basally. Legs orange. Palp with cymbium orange and rest grayish orange. Abdomen gray dorsally and white ventrally. Total length 6.7. Carapace 3.3 long, 3.1 wide. Clypeus 1.0 high. Eye diameters: ALE 0.5, PME 0.6, PLE 0.55.

Leg formula: 2143. Sternum 1.6 long, 1.4 wide. Palpal tibia 0.8 long, 0.5 wide. Palp as in figs 25−26.
